Q

What is the difference between full plans and building notice applications?

A

Building notice: where minor works (without detailed plans) can be carried out prior to approval, with full compliance being ensured at the end of the project.

Full plans: Where full working drawings have been checked and approved by the inspector prior to starting work. If building falls under the Regulatory Reform (Fire Safety) Order 2005, then full plans must be submitted.

A

New buildings

Extensions

Alterations which temporarily or permanently affect ongoing compliance

Certain changes of building use

Underpinning foundations

Material alterations: Alterations to ‘controlled services’ or ‘controlled fittings’ which would result in non-compliance at any stage. A replacement window is an example of a controlled fitting. A boiler is an example of a controlled service.

33
Q

When is building regulations approval required?

A

When you are undertaking ‘building work’ as defined under regulation 3 of the building regulations. This includes:

  • material change of use
  • Insulating cavity walls
  • underpinning
  • consequential improvements

A “controlled service or fitting” means; “A service or fitting in relation to which Part G (Sanitation, hot water safety & water efficiency), H (Drainage & Waste Disposal), J (Combustion appliances & fuel storage systems), L (Conservation of fuel & power) or P (Electrical safety)

37
Q

What are the two types of building regulations approval?

A

Full plans or building notice.

38
Q

When is a building notice required?

A

Where the building work is simple and drawings are not required, this may be appropriate. The building notice enables work to be started without having to provide the local authority with plans.

39
Q

what are the paths through the building control process?

A
  • Local authority building control
  • Licenced approved inspector
  • Competent person
40
Q

Can building regulations approval be obtained after commencing or completing works?

A

Yes, by obtaining a certificate of regularisation, however this may required opening up works.

41
Q

Can works proceed without having received building control approval?

A

Yes, however, work may need to removed or altered if certain aspects are found not to comply with building regulations.

42
Q

Why would you choose the approved inspector rather the LABC route?

A

Fee roughly the same.

If approved inspector then you are likely to have the same inspector throughout.

Typically approved inspectors are more responsive and open to giving advice.

43
Q

How does the process for LABC differ to the approved inspector process?

A

If applying to LABC your architect or engineer will make an application through the planning portal. If applying via approved inspector, they will submit an initial notice to the local authority.

In both instances the employer is responsible for notifying building control when they have reached key stages.

44
Q

What enforcement options are available under building regulations?

A

Criminal offence - can face prosecution and If convicted that person can be fined up to £5,000 for each offence in addition to a daily fine for each day the contravention continues.
